Validators
I found on google.com online validators,
generating precise answers in milliseconds:
for html developers,
checking for errors in mark-up language;
for fortunetellers,
looking for clues in stellar constellations;
for inquisition henchmen,
investigating for deviations of dogma;
for NSA agents,
screening for cue-words of terrorism;
for humanities scholars,
combing for pseudo-mental expressions;
for natural scientists,
trawling for pseudo-logical arguments.
I selected 'Natural sciences',
typing in 'Climate change':
'Climate change is highly speculative,
according to Wikipedia
an exhaustive list of factors,
determining global climatic conditions,
all proven to be conspiration theories.'
